[Hydra][hydra] is a flexible multi-task learning framework written in [PyTorch 1.0][pytorch]. The following multi-objective optimization algorithms are implemented:

* **Naive** — a separate optimizer for each task

* **Gradients averaging** — average out the gradients to the network's body

* **MGDA** — described in the paper [Multi-Task Learning as Multi-Objective Optimization (NIPS 2018)][mgda]

A comprehensive survey on these algorithms (and more) can be found in [this blog article][blog-post].

# Installation

* The code was written on `Python 3.6`. Clone this repository:

      git clone https://github.com/hav4ik/Hydra

* It is recommended to use [anaconda][conda] for installation of core packages (since `conda` packages comes with low-level libraries that can optimize the runtime):

      conda install pytorch torchvision cudatoolkit=10.0 -c pytorch

      conda install numpy pandas scikit-learn

* Some of the packages are not available from anaconda, so you can install them using `pip`:

      pip install -r requirements.txt

# Getting started

* Examples of configuration files can be found [here][configs-dir]. A minimal example is available in [starter.sh][starter]. Execute it as follows (will train with configurations in [configs/toy_experiments/naive.yaml][naive-yaml]):

      ./starter.sh naive 50

# Coming soon...

* Proper framework documentation and examples.
